The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and some pins cannot be used. There are many questions on how to use the ESP32 GPIOs. What pins should you use? What pins should you avoid using in your projects? Input Only GPIOs Pins GPIO34, GPIO35, GPIO36 (VP) and GPIO39 (VN) cannot be configured as outputs. They can be used as digital or analog inputs, or for other purposes. They also lack internal pull-up and pull-down resistors, unlike the other GPIO pins. ESP32 Interrupt Pins All GPIOs can be configured as interrupts.

ESP32 Pinout There are different types of ESP32 development kits available but the function of GPIO pins remains the same across all development boards. You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. ESP32 GPIOs Pinout Guide How to program the ESP32? ESP32 with Arduino IDE Upload Code to the ESP32 using Arduino IDE Introducing the ESP32 First, to get started, what is an ESP32? The ESP32 is a series of chip microcontrollers developed by Espressif. Why are they so popular? Mainly because of the following features: Pinout of the uPesy ESP32 Wroom DevKit board Note A significant difference between the two boards that are not necessarily obvious is their width: The uPesy ESP32 board can be put on a breadboard, and you can access the pins on both sides, unlike most other ESP32 boards that are too "big" to be used on a breadboard. Why do we need to learn ESP32 Pinout? ESP32 based boards come in a variety of shapes and sizes and pinout of each board is different to other. Also, not all pins of the ESP32 Microcontroller SoC will be available on a development board as some pins might be permanently tied to a dedicated function. One such case is the Flash Memory.
ESP32 Tutorials for Beginners
Overview ESP32-DevKitC V4 is a small-sized ESP32-based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-DevKitC V4 on a breadboard. Overview Welcome to the comprehensive guide to the ESP32 pinout. The ESP32 microcontroller is equipped with 48 pins, each serving multiple functions. However, not all pins are readily accessible on every ESP32 development board, and certain pins may have usage restrictions. The ESP32 Technical Reference Manual is addressed to application developers. The manual provides detailed and complete information on how to use the ESP32 memory and peripherals. For pin definition, electrical characteristics, and package information, please see ESP32Datasheet.

ESP32S high resolution pinout and specs Renzo Mischianti
This article on Esp32 pinout reference gives a complete idea about the pinout configuration, the function assigned to pins, what gpio pins we can use. Esp32 chip has 48 pins with multiple functions. Not all the ESP32 development boards have all the pins exposed, and there are some unusable pins. There are many questions about how to use ESP32. ESP32 has a dedicated pulse counter is designed to count the number of rising and falling edges of an input signal. It has 8 channels of PCNT that can be used for pulse counting. You can use any input GPIO pin for PCNT. ADC (Analog to Digital converter) The ESP32 pinout has 2 SAR (Successive Approximation Register) ADC are ADC1 and ADC2.
It's pulled up, so connect to ground to disable the 3.3V regulator. 3V - this is the output from the 3.3V regulator. The regulator can supply 500mA peak but half of that is drawn by the ESP32, and it's a fairly power-hungry chip. So if you need a ton of power for stuff like LEDs, motors, etc. Use the USB or BAT pins, and an additional regulator. Why do we need to learn ESP32 Pinout? ESP32 based boards come in a variety of shapes and sizes and pinout of each board is different to other. Also, not all pins of the ESP32 Microcontroller SoC will be available on a development board as some pins might be permanently tied to a dedicated function. One such case is the Flash Memory.
ESP32 Pinout Reference Which GPIO pins should you use? Random Nerd
ESP32 Pinout: Everything You Need to Know ESP32 is a dual-core SoC with two powerful Xtensa LX6 CPUs that run at up to 240 MHz. It comes with integrated Wi-Fi and Bluetooth connectivity, making it suitable for a wide range of IoT applications that require wireless connectivity. The ESP32-CAM is a development board with an ESP32-S chip, an OV2640 camera, microSD card slot and several GPIOs to connect peripherals. In this guide, we'll take a look at the ESP32-CAM GPIOs and how to use them. Pinout Diagram. The following image shows the pinout diagram for the ESP32-CAM AI-Thinker.
